NASA is restricting the International Space Station’s three crew members to the Russian segment for another weekend as it struggles to find the source of a persistent air leak on the orbiting laboratory.

All of the station hatches will be closed to allow mission controllers to monitor air pressure in each individual module. The National Aeronautics and Space Administration performed a similar weekend hatch closure in August, and on Thursday instructed the crew to perform additional inspections on several windows, seals and valves with specialized detectors.
